After trying dozens of expensive ointments and creams to combat the scaly patches of eczema on my skin, my dermatologist recommended I try fish oil, a.k.a. Omega-3. Within a week my skin was so glowy, it was practically glistening. I couldn't believe a vitamin could have such a major impact on my appearance. Eventually I found myself making a beeline for the back aisle of the drug store to find a random vitamin or supplement—flaxseed oil, hawthorn berries, grape seed extract, whatever—to add to my regimen.

But as much as I love my pills, they are kind of a pain in the ass to manage. My collection of vitamin bottles was getting a little out of control, and I wasn't really sure what was working and what I was swallowing every morning just for the hell of it. So, when Andrea told me about Vitamins on Demand, a company that sends you personalized pill packs for each day of the week, I jumped at the chance to test them.

It's super convenient, and you only have to buy what you want to take. My must-haves are a multi, folic acid, St. John's Wort (good for my mood), ginkgo biloba (good for my brain) and of course my Omega-3s.

What about you? Do you take vitamins everyday? And if so, what are they and and do you think they make a difference in your hair and skin's appearance?
